Specification of Letters Patent. 'Patented Jail. 14, 1919.

Applica-tiamina May 28,1915. seriainasoeea To all 'whom t may concern:

Be it known that l, lll/'Hmmm WRIGHT, a citizen of. thellnited States, residing at Chicago, in the county of Cook and State of llllinois, have invented certain new and useful lmprovements in Draft-Gear Yokes, of which the following is a speeilioation.

flhis invention. relates to improvements in draft gear yokes, and has for its object to PrOVde a device of that nature in which the yoke is provided with an open-hooded forward end constructed to permit the ready insertion thereinto of a coupler butt. y

Still another object is to provide in conjunction with the structure of the type described above, means to lock the coupler against removal from the yoke, sueh means being arranged to permit ready and quick assembliir;` of the struct-nre, as well as easy disassembling. l

Still another object is to provide a device which will permit of the Coupler being` removed from the oar, or applied thereto, without disturbing the draft gear, or the yoke, or in other words, without their having' to be also removed, in either ease.

Still another object is to provide a device which can be applied to oars in service 'without any change in the construction of the car, or its parts.

These and other objects l accomplish by means of the structure set forth and deA scribed in the followingn specification and shown in the. accompafnying` drawings, in which l y Figure 1 is a vertical longitudinal section through one form of my device showing the coupler butt in elevation;

Fig. 2 is a horizontal section through the yoke showing' the coupler butt and draft rigging removed; y l y Fig. 3 is an end elevation of the looking Fig. l is a side elevation, partially in sec tion, of a modified :torni of yoke;

Fig. 5 is a vertical transverse section of the saine;

' Fig. 6 is a view similar' to Figs. 1 and l of still another forni of my invention; and

Fig. 7 is a. vertical tfansverse section through the same.

Like numerals refer to like elements throughout the drawings, in which 10 designates generally my yoke member comprising the strap portions 10a, 10b united at their rear extremities by the rear wall 10. At its forward end the strap 10b is formed with a downturned shoulder or lug 10d. The lower strap 10*1 at its forward vportion is depressed or oifset, as indicated by numeral 10e, this offset portion being apertured, as indicated by ninneral 10f. have showii one form of draft rigging in Fig.' 1, mounted in the yoke 10, the saine being' of well known construction and comprisingfront and back follower plates 11 and 12, respectively, between which is mounted the spring 13. 14 designates a coupler shank terminating in a butt 14:3, hav ing the rear shoulders lll". rlhe yoke 10 is construct-ed with the sides or wings 1()g ex tending` between and formed integral vwith the straps 10a and 10", as shown in Fig. l,

`this construction forming a hooded forward `projecting` shoulder 16" arranged to coaet with the corresponding` shoulder lll" of the coupler butt 14u. This locking block 16 is further provided 'with the o11twardly-pro jeotinp; or shoulder portion 16C on its front face,v the same being intended to abut against the front wall of aperture 10i and strap portion 10'. Below the shoulder portionlc of 'bloek- 16 extends downwardly the front wall 1Gd of block 1G, the same being provided with a ,groove or recess 16e therein. This front wall 16 is provided with a bolt-ing aperture 1G therethrough leadingv from the grooves 16e, see Figs. 1 and 3. The strap portion 10 is [provided with the down-4 wardly-projeetingr shoulder or flange 10, grooved asindicated by numeral 10i, this groove being similar in size and arrangement to the groove 16e in the front face of locking` block 1G which abuts against the rear of shoulder 10,l as shown in Fig'. 1. flhe shoulder ,or wall l()h is also provided with an aperture arranged to aline with aperture 1G, and a bolt or similar member 17 extends through such apertures, being secured in place by the nuts 17 threaded ,thereon. The locking block 16 is constructed with a transverse strengthening rib 16k. The block 16 is arranged so that bearing surface 16a will aline or lie slightly above the plane of` t-he upper surface of strap 10a, so that under eXtr'eme buliing strains the coupler i butt 14a will ride over upon the strap 10a,

' cated by numerals 10. A locking block 20 fits in the aperturelOf; this locking block, as in the case of block 16 described above; has the'bearing surface 20, at one end of which is provided the upwardly extending shoulder 20". This. `locking block 20 is provided with the longitudinal groove 20d at its underside, 'as shown for example in Fig. 5, and a tapered key 21 is driven through apertures 10m, and through the slot 20d, serving to prevent displacement of the lockingblock 20 lwhen the structure is assembled. A cross key or pin 22 may be driven through an aperture 21a adjacent one -end of the key 21 and forwardly of the forward flange 10m, as shown in Fig. 4. The operation and arrangement of the structure shown in Figs. 4 and 5 is similar to that of the structure shown in Figs. 1 and 3, and needs no further description herein.

In Figs. 6 and 7 I have shown still another modification inwhich the portion 10 of strap 10a is provided with the aperture 10f. Projecting outwardly from the strap portions 10e are the side flanges 10, provided with bol-ting apertures 10D and reinforced by` transverse ribs 10P, see Fig. 7. A locking block 30 is provided having outwardly-directed flanges' 30a arranged to lie b'elow flanges 10, and provided with bolting apertures 30b alining with apertures 10p for insertion therethrough of the locking bolts 31 carrying the nuts 32 threaded thereon, as shown in Fig. 7 The central portion of the locking block 80 extends upwardly into the hooded end of the yoke and is provided with the flat bearing surface 30G, terminating at one end in the upwardly'extending shoulder 30d. This bearing surface 30 is substantially in alinement with the upper surface of yoke strap'10a, and the operation and functioning of this structure is similar to that shown and described in connection with the other forms.

While -I have shown and described several 'embodiments of my invention, it is obvious that it is susceptible of other modifications, such as arranging the key 21 laterally instead o parallel with the center line of the yoke, as has been shown in Fig. 4, or the substitution of pins or bolts in lieu of the key,or the substitution of a key for the boltyin Fig. 1,-in either case, so that I do not wish to be restricted to the form shown or described beyond the scope of the appended claims.

1. A yoke having a hooded forward end constructed to permit insertion therein of a coupler butt, said hooded end being formed with an engaging lip and an aperture, a locking member attached to said yoke and project-ing through said aperture, said locking member being provided with a shoulder coacting with said lip to prevent removal of a coupler butt from said yoke, said hooded end of said yoke being provided with a projecting flange, and means to attach said locking member to said flange.
